JpaPersistenceUnit

We now need to create the Persistent Unit definition. We are going to create a file called persistence.xml in the src/META-INF directory with the following contents:

persistence.xml

<persistence>
    <persistence-unit name="examplePersistenceUnit" 
                      transaction-type="RESOURCE_LOCAL">
        <properties>
            <property name="hibernate.show_sql" value="false" />
            <property name="hibernate.format_sql" value="false" />
 
            <property name="hibernate.connection.driver_class" 
                      value="org.hsqldb.jdbcDriver" />
            <property name="hibernate.connection.url" 
                      value="jdbc:hsqldb:mem:mem:aname" />
            <property name="hibernate.connection.username" value="sa" />
 
            <property name="hibernate.dialect" 
                      value="org.hibernate.dialect.HSQLDialect" />
            <property name="hibernate.hbm2ddl.auto" value="create" />
        </properties>
    </persistence-unit>
</persistence>

The Steps

1. Expand your <project>
2. Select the src directory
3. Find the src/META-INF directory (if one does not exist, right-click, select New:Folder, enter META-INF and press enter)
4. Right click the src/META-INF, select new:File.
5. Enter persistence.xml for the name and press "OK" (Note: all lowercase. It won't make a difference on Windows XP but it will on Unix.)
6. Copy the contents (above) into the file and save it
